IMPROVED GONG-BELL.

Spceili cation forming part of Letters Patent No. 58,580, (lated 'October 9, 1866.

To all whom it may concern:

Be it known that I, ISAAC A. BEVIN, of Chatham, in the county ot' Middlesex and State of Connecticut, have invented a new and useful lmprovementin Gong-Bells 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a plan or top view of my invention 5 Fig. 2, a front elevation of the same, the bell A in both views being partly broken.

Similar letters ot' reference indicate like parts.

The object of my invention is to construct a gongbell of that class in which the bclapper strikes twice by one pull, so that a powerful spring may be employed and a heavy blow may be struck upon the bell, while the pull ot' the bell will be easy and effective.

My invention consists in the construction of gong-striking apparatus in such a manner that the pull will act between the spring and the clapper, as hereinafter described.

The bell A is connected by means ot' the supportingpin a with the bed-plate B, as seen.

The clapper is composed of a wire rod c, one portion thereof being wound spirally around a pivot, d. The lower end of the wire diverges from the coil, and is formed into a loop, d', into which the end of the spring C is hooked. The extremity of the elapper-wire forms a stop, d, which rests against a stop-pin, e, by which the necessary recoil is given to the clapper when the latter is operated.

The loop d also acts as a stop, and strikes against the pin c when the clapper is operated.

A hook, f, resting ony the pin c, holds the coil of the clapper-rod upon the pivot d, and the hook is turned out of the way when the clapper-rod is to be taken oft" from the pivot d. .The bell-pull i is attached to the loop g of the spring C between the spring and the clapper-rod, and when force is applied to the pull the end of the spring and the loop d of the clapper-rod c is drawn toward the pin c', and the hammer b strikes the bell. On the release ot' the pull the spring then throws back the clapper until the hammer strikes the bell the second time upon the opposite side thereof, when the end of the clapper-rod c comes in contact with the stop-pin c, in which position it is represented in the' drawings. y

In other gong-bells it has been common to arrange the pull of the bell outside of the spring and outside ot' the clapper, which arrangement renders it very difficult to operate such bells, as much power is required to overcome the resistance of the spring. My invention removes this difficulty, as the pull acts between the spring and the clapper, and consequently does not require the whole spring to be pulled forward, thereby allowing the use of a strong spring, but requiring little power to operate the same.

By attaching the pull directly to the loop d', as shown by dotted lines in Fig. 1, substantially the saine effect would be produced.

Having thus described my invention, I claim as new and desire to secure by'Letters Patent- The construction of the gon g-striking apparatus, substantially as herein shown and described, so that the pull will act between the spring and the striker, all as set t'orth.

The above specification ot' my invention signed by lne this 7th day of August, 1866.

ISAAC A. BEVIN.
